TCS, India's largest software exporter by sales, has hit back at brokerage house CLSA's IT sector downgrade.

The company's investor relations team sent out a mail to equity analysts stating that it hasn't witnessed any weakening of demand and that visa issues, though an irritant wasn't disruptive enough to justify a sudden sector downgrade. ET NOW has a copy of the mail sent by TCS.

The mail follows a report released by CLSA on Monday, where it gave a thumbs down to the entire IT sector citing macro-economic worries, visa issues and unsustainable valuations. In its report, CLSA downgraded the sector from neutral to underweight and TCS & Infosys to underperform.
